Crab's crab is very delicious. There are yellow things in the crayfish head. Is it shrimp yellow? Can I have shrimp yellow? What food can't crayfish drink together? Let's have a look with Xiaobian.
What's yellow in crawfish's head
The yellow in the head of crayfish is shrimp yellow, which usually appears in the head of mature mother shrimp.
In fact, shrimp yellow is the ovary of mature female shrimp. The unproductive shrimp (i.e. eggs) will contain shrimp yellow at the head and neck when the brain female shrimp reaches maturity, so the shrimp with shrimp yellow must be the female shrimp, but without shrimp yellow, it is not necessarily the male shrimp, and the female shrimp can not see shrimp yellow when it is immature. Crawfish's head is full of brain, heart, gonad, digestive gland, stomach and antennal gland and other miscellaneous organs. And the prawn yellow that the prawn head pie adores is actually the digestive gland of crayfish, that is, the liver and pancreas of prawn.
In fact, prawn yellow is rich in unsaturated fatty acids, protein, microelement selenium, and various vitamins. It still sounds great, doesn't it? Unfortunately, the reality is always cruel. Crayfish has a higher concentration of heavy metals than grass carp and crucian carp. Because of water pollution, heavy metals are concentrated in exoskeleton and liver. In order to enjoy crayfish safely, we must select the ones that are cultured in the environment with better water quality, and try our best to eliminate the shrimp heads and do not eat them.
Can I eat the yellow in the head of crayfish
Shrimp yellow itself is completely edible, but not recommended.
Because shrimp yellow is closely connected with the liver of shrimp, it is difficult to separate, and the liver is the detoxification organ of shrimp. Therefore, experts suggest that people try to eat as little or no shrimp yellow as possible, not in order to pursue the fresh taste and harm the health of the body.
The yellow on the head of crayfish can't be eaten. The circulatory system, respiratory system and reproductive system of shrimp are all concentrated in the head and chest, and the abdomen can be said to be just a moving organ. From an Ankang point of view, it is not recommended to eat the head of shrimp. In addition to the sediment, there are risks such as parasites. The black line on the back of the abdomen of shrimp is its intestines, which of course is the poop of shrimp. It should be removed before cooking.
Crayfish can't be eaten with anything
Foods rich in vitamin C
The crayfish and shrimp meat contains high concentration of arsenic compounds, which are harmless to human body. However, if a large amount of vitamin C is taken at the same time, the arsenic compounds will be oxidized to arsenic trioxide, which is also known as arsenic trioxide, which will lead to acute arsenic poisoning. Therefore, in two hours after eating crayfish should not be too much vitamin C content of food. Common foods with high vitamin C content include kiwifruit, Rosa, orange, grapefruit, mango, tomato, persimmon, red dates, etc.
Foods with high tannic acid content
Crawfish and shrimp meat contain high protein, calcium, phosphorus and other nutrients. If they are eaten together with foods with high tannic acid content, calcium and tannic acid will react to form calcium precipitate that can be digested, which will not only reduce the nutritional composition of shrimp meat, but also combine calcium and tannic acid to form a substance that is not easy to digest, leading to vomiting, dizziness, nausea, abdominal pain and other symptoms 。 In addition, a large number of proteins will react with meat to form insoluble complexes, a small amount of which will not affect health, and a large amount of which can form gastrolith. Common tannic acid foods include persimmon, tea, grape, pomegranate, hawthorn, etc.
High protein food
We all know that crayfish is a kind of high protein food, which contains a lot of high-quality protein. If we eat a lot of high protein food at the same time, it is easy to increase the load of gastrointestinal and liver and kidney, especially the people with poor digestive function and liver and kidney function can't eat like this. The light ones suffer from abdominal distension, diarrhea and other dyspepsia, and even lead to liver and kidney failure. Common high protein foods: milk, eggs, soymilk, animal lean meat, etc.
